The Nightsabers, Strigid Owls, and Webwood Lurkers which drop the items can be found all around Dolanaar, so this quest is a good one to do while traveling for other quests. The items also drop off of the higher level versions of these creatures, found further from Dolanaar.

Once all the items have been collected, return to Zenn Foulhoof to turn in the quest.
